Ramon Llull was born in 1232 in Majorca, now part of Spain. He was a logician, philosopher and theologian. Llull was convinced that it was possible to “compute” truths by creating an “alphabet” to represent basic concepts and then using a mechanical “calculator” to manipulate the symbols and reveal the truth. His calculator was comprised of several concentric circles with the alphabet symbols on them. By rotating the circles independently, different combinations of symbols could be created and were used to represent a process of abstract reasoning or “calculating”. Llulls work on this project inspired Leibniz to continue it hundreds of years later.
